Performance analysis and multi-mode control of grid connected micro Wind–solar hybrid generator in Saudi Arabia

Abstract

The objective of this paper was to study and analyze the performance of a micro Wind – Solar Hybrid Generator (WSHG) in the Kingdom of Saudi Arabia (KSA). The WSHG consists of a micro wind solar system connected to a secondary distribution grid. The system was tested in two locations in the KSA namely DAMMAM and HA`IL and used the wind speed and solar radiation of two periods of the year. Two operating modes were discussed for the system: the Normal Operating Mode (NOM) and the Default Operating Mode (DOM). The simulation results showed the best performance of the system during the two periods of the year, in the two locations of the KSA, and in the two operating modes. The experimental measurements of the WSHG have been carried out and showed the similarity between the measured and simulated values of the output inverter voltage and of the DC-link voltage.
